Become a PHIUS Certified Builder!

Superinsulation, air-tight envelopes, high-performance window installation, site management, component sourcing--passive house construction presents special challenges to builders. The PHIUS Builders Training program prepares construction professionals to meet the passive house challenge.

Dan Whitmore, Mike Kernagis, and Natalie Leonard--who have built 25+ successful passive house projects between them--developed the curriculum. It runs from an introduction to design theory and climate-specific detailing to materials, techniques, project management, and quality assurance.

The course offers real-world experience in the on-site implementation of passive house as well as counseling and advice to both the practical and business concerns specific to passive house. The course covers not only craftsmanship, but also focuses on the risks and liability to the passive house contractor and guidance in both problem solving and (more importantly) problem avoidance.

Full Program:

  • Four full days of in-class instruction (Yestermorrow only, see schedule below)

Course Highlights

  • Learn general passive house principles
  • Classroom and field focus on envelope issues
  • HVAC considerations and testing
  • Cost optimization/bidding
  • QA/QC process


To become a PHIUS Certified Builder, students must:

  • Complete and return the qualifying exam within three weeks of completing class (exam requires separate registration, see below)
  • Earn a passing grade of 75%
  • Provide proof of licensure & insurance for jurisdictions where they are required

Maintaining the PHIUS Certified Builder Credential 

A nominal maintenance fee will be billed on a yearly basis starting on January 15, 2018. One listing fee will be due per professional regardless of the number of certified credentials held by that professional. (For example a CPHC® who is also a Builder, will be subject to a single maintenance fee.)

The fee will help maintain and improve the listing database and assist in the development of the continuing education programs for all professionals.

PHIUS Certified Builders can maintain/extend their certification status through either one of the following methods:

1. Build a PHIUS+ Certified Passive Building Project

Successfully building a project within three years after the professional’s certification date will maintain/extend the Builder’s professional credential status by an additional three years.

2. Take and Pass the Current Builder Exam

Successfully completing the Builder exam will maintain/extend the Builder’s professional credential status by three years. 


If Builder Certification Expires:

  • A Builder who fails to meet one of the above requirements by their expiration date will be removed from the Builder database and their credential will no longer be considered valid.
  • A Builder whose certification status has expired can reactivate their certification by taking and passing the current Builder exam.
